IRAN K PEREBENDA, OF HARRISON; NEW JERSEY LOCK Application. fi1 e d March'-25,- 1929. Serial -No.-349,564.--=

The invention relates to locksand the .primary object of theinvention isltorprovide-a simple. and novel, lockstructurle having a plurality of bolts...

A further, obj ect. of the invention is to. pro-1 vide alockhaving a pair of sliding bolts, one

being telescopic Within the other and said bolts being adapted tobesuccessivelyv projected and retracted by -a single key.

Another object ofthe invention is .to providea lock ofthe character stated having arelatively small number of parts capable of convenient and .economicaLmanufacture and assemblage; which is strong and durable and not likely to get out; of working order.

Withzthe abovegeneral objects in view and others that, will appear as the nature a of the invention is better understood, the same consists of. the ,novel construction, combination and arrangement of parts hereinafter more a fully described, illustrated in the, acoompanying drawings and pointed out n .the appendedclaims, v

Referring to the drawings in detail, the

loclqasshown, comprises a casing 11 having.

a removable .frqnthplate: 12 formed with the usual. 7 key-hole and connected to e the casing proper as by rneansof screws 13.; The casing has the usual edgeplate.Handboltslot.l A bolt 15. of substantially channel. shape and cross-section having top. and-bottomflanges 16-and 17 receives forv telescopic sliding moveinent therein a plain bolt 18. f Thesebolts are:

slidablebeneath a pair of straps 19"and. 20.

near opposite ends'of the casing and secured:

to the back thereof. The strap 20 is mounted on a raised portion or plate 21; beingdetaeh-n ably secured in position at-itsangulai' bent endsas by meansof pins or screws 22;; This strapris preferably stamped fromia blank of sheet metal havingan extension at one-end.

formed into a right angular retaining plate M- 23. provided with an opening receiving a piyot ,pin'24. This pin carries'a pair of springsp 25 which are curvedvup and gaged at the ups per end of the casing and thespringinetal f strips forming the same-are coiled about the pivot 24 andhaving portions 26 extending. above bolts'while their free ends eareibent r downwardly at right angles as indicated at M 27. The bolt-15-is provided with a longitudinal slot 28 and the bolt 18 hasia correspond-v ing slot 29:which receivesa substantially U-- one..leg: longer than the other. The' longere shaped guiding and limiting member-3O with leg extends through an opening 31' in: the

strap 20 and into :a corresponding opening-in athe plate 21 and this part serves to guide the bolts in their 1I10V6Hl811tS-aS -WBH as to limit. suchlmovementsin opposite directions: eEachpart26 is formed with a wing or plate portion.

andhaving a concaved recess33zin its bottom v edge.

.32 shown substantiallytriangular inshape 1 Atthe'top portion ofthebolt 15 the flange 16 is cutawayras indicatedat Mandprovidedwitha pair of notches 35-and 3'6at eachend of thisrecess orient away. portion. .Th'e'botill) tom flange-l7 is also cut awaya sindicated-at 37 for a considerable length intermediate-l of its ,ends and provided With relatively 1 eep notch or recess38m- The'bolt 18 hasapair of topnotches 39 and 40 andnone-flace is pro-. vided with .a concaved recess 41 intermediate- 1y .ofitslength adjacent the recess 37 and.

with a relatively wide and deep notch42 in" the thinuwalleof the boltthus..pr ovided at ithearecess 41. Thexwingswor plate portions 1' 32 as is noted from the drawings, are gaged on opposite sides of the bolts and serve to retain them in a similar relation and guide them in their telescopic movements.

At the key-hole is provided a semi-circular bearing plate or tumbler support 43 which is secured to the back of the casing as indicated at 44 and comprises spaced portions between which a nib or wing 45 or a key 46 is designed to move in an arc. The key also has a nib or wing 47 with projections 48 and 49 extending in opposite directions and 10- cated at different radial distances from the axis. The plate 43 has a circular boss 50 around the circular part of the key-hole and receives thereon the circular portion 51 of a tumbler having a relatively thin slotted extension or wing 52 and another wing or arm 53 with a lug 54 projecting forwardly at right angles and of segmental shape as well as provided with a recess or groove 55 in its outer edge.

In the operation of the lock the key is inserted with the wing 47 disclosed in the slot of the wing 52. The wing 53 is thus in position to engage the notch 42 of the bolt 18 and the recess 55 receives the edge 33 of the-adjacent Wing 32. The bolts being retracted, the member 30'is near the front ends of the slots 28 and'29 and the springs 25 force the bent ends or catches 27 into the front notches 25 and 40 of the bolts 15 and 18, respectively. By turning the key, the wing 53 engages'the front end of the notch 42 and projects the bolt 18, the catch 27 being first disengaged from the notch 40 as the lug 54 engages the wing 42 and raises the portion or arm 26 against the action of its spring 25. During this operation the bolt 15 is stationary and the bolt 18 slides therein. (Jontinued rotation of the key results in the wing 45 engaging the opposite plate 32 at its recessed edge 33 so as to disengage the other catch 37 from the notch 35 of the bolt 15 and then the wing 45 engages the notch 38 to project the bolt 15 while the wing 52 slides in a recess-41 and between the bolt-18and the adjacent plate 32. At this time the projection 49 rides against the edge of the bottom bolt 18 and the projection 48 continues in engagement with the recess in the outer plate 32 so as to keep both catches 27 raised until they are released and snapped into the notches 36 and 39, thus holding the bolts 1 locked in projected positions and against retraction or withdrawal except by the use of the proper key.

In retracting the bolts, the key is inserted and the reverse action takes place in the reverse order, the catches 27 being first disengaged from the notches 36 and 39 and the bolts retracted by engagement of the wings and respective notches 38 and 42 until the catches 27 snap into the notches 35 and 40. When the bolts are projected the slots 28 and 29 will be at their forward limit as shown: on Fig. 3.

It will thus be seen that I have provided: a very simple lock structure embodying a plurality, preferably two sliding bolts telescopical with relation to one another and als0- a lock which comprises relatively arts which can be manufactu'rd't'vith f cllity' and which'are simple and not likely to get out of working order. p c
